SIGNAL-MACHINE.

SPECIFICATION forming part of Letters Patent N0. 303,266, dated August 12, 1884.

Application filed April 30, 1883. (No model.)

To all whom it may concern;

Be it known that-we, HIRAM G. XV. Cow- DERY, of the city of Chicago, in the county of. Cook and State of Illinois, and JosEPH H.

Bacon, of the city of Charlotte, in the county of Eaton and the State of Michigan, havejointly invented a new and useful Signal-Machine, of which the following is a specification.

Our invention relates to improvements in m signals for day and night use, in which the shade covering the lamp rotates, for the purpose of exhibiting diii'erent-colored lights in the night-time, in conjunction with the target, which serves as an indicator in the day-time,

all of which is operated from within the station-house by meansoi' a crank-lever; and the objects of our improvements are, first, to provide a firm and stationary seat for the lamp 5 second, to revolve the shade and target, while the light remains fixed and stationary; third, to protect the gear operating the signal from the rain, sleet, and storm; fourth, to prevent the light from being jerked out by revolving; fifth, to insure certainty and ease of operation;

sixth, to provide a signal in which the shade used is so ventilated thatmoisture and soot will not gather upon the inside of the lenses and obscure the light. We obtain these ob-. jects by the mechanism illustrated in the ac 3Q oompanying drawings, in which Figure l is a sectional view of the signal. Fig. 2 is a sectional view of the collar. Fig.

3 is a detailed view in perspective of the col- Fi 7 isa )ers ective view of the quarter cars 1 P g wheel. Fig. 8 is a perspective view in detail of the shade containing the lenses of'different color, which is bolted fast to the wheel, Fig. 7, and revolves about the lamp.

Similarlcttcrs refer to similar parts throughout the several views.

The collar D, Figs. 1, 2, 3,'and G, has asocket in one end for receiving the bolt, Fig. 1, screwed onto the end of the rod L, which is riveted to the target (7, and passes up through The rod L, Figs. 1 and 6, has a thread out upon the top end for receiving the nut N. A pin passes through the nut N and the rod L to'prevent the nut N from becoming loosened. The cup E, Figs. 1, 4, and (i, has an inside thread, so as to screw down on thccollar D, and has a flange on the top for receiving the lamp.

The wheel H, Figs. 1, (3, and 7, has cogs onefourth theway around it, into which the gearwheel B, Fig. 1, meshes,- also, a hole, '2', made for receiving the guide-rod K, Fig. 1, attached to the target 0, and holes 4 4 4 4.. for bolting on the shade A, Fig. 8.

The shade A, Figs. 1 and S, is constructed of galvanized or sheet iron or tin, provided with lenses 1, and ventilated at the top by perforated holes ff f through the iron, and at the bottom by apertures 71. h h through the shade,

where the bottom is fastened on, and through the holes h h h in the bottom. The shade A has a lining, M, upon the inside, extending up to the bottom of the lens, made so as to have aspace, g, Fig. 1, between the shade A and the lining M. The lining M is soldered below to the bottom I) of the shade A, and is fastened at the top to the shade A only at points be tween the lenses, as 7.: it, by strips of tin soldered to the lining M and the inside of the shade A. The bottom I) is extended so as to cover the wheel H, and has holes in the bottom suitable for bolting it to the wheel H through the holes 4 at 4 4, and a hole, 12, in the center for receiving the collar D. The shade A contains two different-colored lenses, and is made to exhibit a different-colored lightsimply by turning the shadeA about the stationary lamp Q. The target 0 is made. to turn one-quarter way around, and to stand at right angles or parallel with the track, as desired.

In the further construction of our invention we attach the crank-lever c, Fig. 1, to the rod a, which sets in a socket in the table in the station-house, by a key or pin, so that the lever 0 will not turn without turning the rod a. v \Ve then screw the bracket T to the building, and secure the gear-wheel w to the rod a, so as to turn with the rod a. We then bolt the journal-box J on the arm B, and pass one end of the rod 0 through the journal-box J and the other end through the bracket T, and attach the gear-wheel m on the rod 0, so as to mesh into the gear-wheel n, and the gear-wheel B to the other end of the rod 0. Both gearwheels B and m are attached to the rod 0 with keys or pins, so as to turn with the rod 0. The arm B, as attached to the building, has a mortise, 00, cut through it, within which turns the gear-wheel R, and a hole bored near the end, through which passes the target-rod L.

To the target 0 is riveted a short iron rod, K, flattened at the end attached to the target 0, and extending up through the wheel H, Figs. 1, 6, and 7, at 1-. We now fasten the bracket S under the arm B, and we fasten upon the arm B the collar D, slightly mortiscd into said arm B, by screws or bolts over the hole bored through said arm B for receiving the rod L, as shown in Fig. 3. The rod L, secured to the target 0, with the guide-rod K attached, is then passed up from beneath through the bracket S, the arm B, and the collar D far enough to screw on the nut N and to put through the pin 1), and is then returned back The into the collar D, as is shown in Fig. 1. wheel H, Fig. 7, is then placed on the collar D, Figs. 1, 3, and 6, with the guide-rod K,

Figs. 1 and 6, extending up through the hole 1" in the wheel H, Figs. 1 and 6. Next we bolt the shade A onto the wheel H at i 4 4 4, and screw the cup E, Figs. 1 and 6, onto the collar D. We now nailthe cup G, Fig. 5, over the gear R and journal-box J into the arm B. The target 0 is operated by the guide K, passing up through the wheel H at T, which in turn meshes into the gear-wheel It, as shown in Fig. 1.

For operating the device shown, we take hold of the crank-lever 0 upon the operators table 6, which has been connected with the mechanism intended to work the signal, as before set forth and illustrated, and turn it to the right or left one-quarter way around, which also turns the gear-wheels n, m, B, and H quarter way round, and so revolve the shade A, which is bolted to the wheel H, and the target 0, which is also connected with said wheel H, one-quarter wayaround.

Having thus described our invention, what we claim, and desire to secure by Letters Patent is An improvement in signals, consisting of the combination of a rotating shade with a lining upon the inside, ventilated around the bottom from the outside and beneath, a gearwheel for supporting the shade and guiding the target, and a stationary collar to support the light about which the shade revolves, with suitable machinery for operating the same, substantially as set forth and described.
